Polysexuality is the attraction to multiple genders. A polysexual person is one "encompassing or characterized by many different kinds of sexuality."[1] Authors Linda Garnets and Douglas Kimmel state that polysexual is a sexual identity "used by people who recognize that the term bisexual reifies the gender dichotomy that underlies the distinction between heterosexuality and homosexuality, implying that bisexuality is nothing more than a hybrid combination of these gender and sexual dichotomies."[2] However, it is arguable that bisexuality does not actually enforce a gender dichotomy. Bisexual activists will often argue the "bi" part can refer to genders which are the same and genders which are different.[3]

Polysexuality is distinct from polyamory, the desire to be intimately involved with more than one person at once, or pansexuality, which is attraction to all genders and sexes. Polysexuality encompasses many, but not necessarily all, sexualities.[4]

Polysexuality is a self-identifying term that is somewhat amorphous,[5] as there is a wide variety of different people who use the term to describe themselves.[6] Polysexual identity is related to gender identity and is used by some people who identify outside the binarist gender spectrum. People who refer to themselves as polysexual may be attracted to transgender people, third gender people, two-spirit people, genderqueer people, plus people who are intersex. However, polysexuality does not have to be the exclusive attraction towards non-binary genders or sexes, though it can be.[citation needed] People who identify as polysexual may still be attracted to one or both binary genders or sexes.

The relationship between religion and sexuality varies widely among belief systems, with some prohibiting polysexual behavior and others incorporating it into their practices.[7] Major monotheistic religions generally prohibit polysexual activity.[7]
